Frequently Asked Questions
1. How do the different sizes of gelatin capsules affect their uses?
The size of gelatin capsules determines the amount of powder, liquid, or other substances they can hold. Larger capsules can hold more material, making them suitable for higher dosages, while smaller capsules are often used for lower dosages or when taking up less space in the stomach is desired.
2. Can gelatin capsules be used for both dry and liquid substances?
Yes, gelatin capsules can be used for both dry powders and liquid substances. However, it's important to note that the capsule should not be filled with a very liquidy substance as it may leak, and it's also not recommended to use hot liquids as it can cause the gelatin to melt.
3. Are there any dietary considerations when choosing gelatin capsules?
Yes, dietary considerations are important. Gelatin is derived from animal collagen, so vegetarians and vegans may prefer to use plant-based alternatives like vegetarian capsules made from materials like hypromellose (a type of cellulose). Additionally, some people may have allergies to gelatin and should opt for suitable alternatives.
